Answer:
Below:
Explanation:
Consider two rays originating from the bottom of the pond. As these rays get refracted into the air, they bend away from the normal. ... This point gives the apparent position of the bottom of the pond, therefore, the pond appears to be shallower.

The Basketball with the greatest gravitational potential energy is : Basketball 4 feet above the ground ( c )
<u>Given data :</u>
masses = constant
H₁ = 2 ft
H₂ = 3 ft
H₃ = 4 ft
g = 9.81 m/s²
<h3><u>Procedure to determine the basketball with the greatest gravitational P.E </u></h3>
we will apply the equation below
Gravitational potential energy ( U ) = mgh
U = 2 * 9.81 = 19.62
U = 3 * 9.81 = 29.43
U = 4 * 9.81 = 39.24
From the calculations the basketball with the greatest gravitational potential energy is the basketball at 4ft above the ground

The resultant in the x-direction:
Rx = F1 + F2 = 2.5 N - 1 N = 1.5 N .
The resultant in the y-direction:
Ry = F3 + F4 = 2 N - 3 N = -1 N.
We know, For a substance they both are equal in magnitude, i.e.,
Specific Gravity = Density
Specific Gravity = 19.3 [ As Density = 19.3 ]
In short, option C would be your correct Answer!
Hope this helps!
Thermal energy, creates steam or pressure, therefore, if in a small space it creates pressure within its "shell"
